A megaureter is a descriptive term meaning large ureter and is diagnosed by ultrasound. Megaureters can be classified as obstructed, refluxing, obstructed and refluxing, or neither obstructing nor refluxing. We aimed to evaluate the outcomes of children with non-refluxing non-obstructive (NONR) megaureter.

Material and methods:

Hospital files of the children with NONR megaureter were evaluated retrospectively for age at diagnosis, presenting complaint, follow-up period, accompanying urologic abnormalities, complications (renal scar and urinary tract infection) and final status.

Almost half of the NONR megaureters resolve spontaneously. The most frequent complication of NONR megaureter was urinary tract infection. On the other hand, the rate of renal scar and decreased renal function was low.
